[X86][AVX] SimplifyDemandedVectorElts - handle extraction from X86ISD::SUBV_BROADCAST source (PR42819)

PR42819 showed an issue that we couldn't handle the case where we demanded a 'sub-sub-vector' of the SUBV_BROADCAST 'sub-vector' source.

This patch recognizes these cases and extracts the sub-sub-vector instead of trying to broadcast to a type smaller than the 'sub-vector' source.

While e.g. __sanitizer::internal_lseek is defined in sanitizer_solaris.cc, g++ 9
predefines _FILE_OFFSET_BITS=64 while clang++ currently does not.

This patch resolves this inconsistency by following the gcc lead, which allows
make check-all to finish successfully.

There's one caveat: gcc defines _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE for C++ only, while clang has long been doing it for
all languages.  I'd like to keep it this way because those macros do is to make
declarations of fseek/ftello (_LARGEFILE_SOURCE) resp. the 64-bit versions
of largefile functions (*64 with _LARGEFILE64_SOURCE) visible additionally.
However, _FILE_OFFSET_BITS=64 changes all affected functions to be largefile-aware.
I'd like to restrict this to C++, just like gcc does.

To avoid a similar inconsistence with host compilers that don't predefine _FILE_OFFSET_BITS=64
(e.g. clang < 9, gcc < 9), this needs a compantion patch https://reviews.llvm.org/D64483.

the locking the module mutex. While it may be nice doing the locking in
a central place, we weren't really succesful in doing that right now,
because some SymbolFile function could still be called without going

battle-tested symbol file implementation) roughly a half of the
functions was taking additional locks and another half was asserting
that the lock is already held. By making the SymbolFile responsible for

consistent.

[DivRemPairs] Handling for expanded-form rem - recomposition (PR42673)

Summary:
While `-div-rem-pairs` pass can decompose rem in div+rem pair when div-rem pair
is unsupported by target, nothing performs the opposite fold.
We can't do that in InstCombine or DAGCombine since neither of those has access to TTI.
So it makes most sense to teach `-div-rem-pairs` about it.

If we matched rem in expanded form, we know we will be able to place div-rem pair
next to each other so we won't regress the situation.
Also, we shouldn't decompose rem if we matched already-decomposed form.
This is surprisingly straight-forward otherwise.

5 years ago[DivergenceAnalysis] Add methods for querying divergence at use
Jay Foad [Mon, 29 Jul 2019 10:22:09 +0000 (10:22 +0000)]
[DivergenceAnalysis] Add methods for querying divergence at use

Summary:
The existing isDivergent(Value) methods query whether a value is
divergent at its definition. However even if a value is uniform at its
definition, a use of it in another basic block can be divergent because
of divergent control flow between the def and the use.

This patch adds new isDivergent(Use) methods to DivergenceAnalysis,
LegacyDivergenceAnalysis and GPUDivergenceAnalysis.

This might allow D63953 or other similar workarounds to be removed.
